  Though the cavitation as a damaging phenomenon of hydraulic devices, has been drawing the interest of many researchers, almost very few investigations have been done on the cavitation measurement inside axial flow pumps. The present study is one of the leading ones which consider this phenomenon inside this widely used type of pumps. Oscillations of the structure of the pump were used to measure the cavitation. An average energy method for identification cavitation occurrence and measurement its intensity has been developed. This is called Logarithmic Cavitation Intensity (LCI). A statistical analysis was undertaken in a both time and frequency domains and the LCI was proved as a proper criterion for defining the cavitation intensity. Though being very robust, the introduced method is very simple and does not require time consuming calculations. This causes LCI method to be feasible by simple hardware with low sampling frequency, resulting in reducing the computational time as well as hardware complexity and cost.
